I have a problem in an assignment (already active for students) that is creating difficulty; it involves reading a value from a graph, and for some students it seems to be rejecting values like 4, claiming the answer is something like 3.999999.
I need advice about how to fix the score for students being affected like this - I see no way to override the give score? Or, will it work at this stage simply to delete the problem from the set, or will that mess the grades of students who have already completed the assignment? Any other way of dealing with this?
Help would be appreciated!
